My invention relates to conveyer rollers of the type used in connection with gravity conveyers, and has for its principal object to provide for the cheap and simple manufacture, mounting and replacement of the rollers. It consists principally in providing the end plugs of the rollers with non-circular recesses to receive non-circular bushings for the supporting spindles whose ends bear if; against the bottoms of said recesses.

ln the accompanying drawings wherein like reference numerals refer to like parts wherever they occur,

Fig. l is an end elevation of a gravity conis veyer embodying my invention;

F ig. 2 is a. vertical cross-section of part of the conveyer showing a conveyer roller in longitudinal section;

Fig. 3 is an end view and Figxd is a fragac mental sectionalvview of a` roller with the bushing remo-ved therefrom; and

Fig. 5 is a cross-sectional view of a roller on the line 5*5 of Fig. 2.

In the construction illustrated, the conveyer roller has its ends mounted on spindles l that are spaced apart andadjustably mounted in the spaced side rails 2 of the conveyer frame, such spindles being locked in adjusted Y position by nuts 3 that are screwthreaded so thereon on opposite sides of the side rail.

The roller illustrated comprises a vtubular body l having its ends closed by circular plugs 5 that lit in the ends thereof. Each plug has a circumferential ange 6 that overlaps and bears against the end of the tubular body. The outer face of each end plug has a recess 7 into which the spindle enters and against the bottom of which the end'of the spindle bears. This recess is of hexagonal or other polygonal or non-circular section and has fitted therein a bushing 8 of similar sectional outline, whereby the bushing is locked against rotation relative to the end plug but may be moved aXially'thereof. The bushing is provided with a central bore of propersize to fit the inner portion of the spindle and serve as a bearing therefor. The inner end of the spindle is rounded or coned to a thrust bearing surface of small area that cooperates ce with the center portion of the recess in the end roller, the wear onall sides ofthe bore of the cap;v and atithe side .of the circumferential tween them is avoided, and it is easier and.

cheaper to adequately fit theseparts together than would be necessary if the recess and the bushing were of circular outline. As the bushing is thus compelled to revolve with the bushing is equal and the roller is thus kept concentric with the axis of the spindles. lt' is also noted that the bushing is easily ace cessible and removable and interchangeable; and `it may be made of bronze or other rust-,

Another advantage is that the space in the end plug baclr'of the bushing is available as a chamber for lubricating grease. t is also noted that the plug completely closes the end of the roller and thereby prevents liquids from getting into the interior of the roller and causing corrosionthereof or souring or ldecaying and rendering the device unsanitary or causing offensive odor.

What I claim is:

- l. A conveyer roller comprising a tubular body, end plugs therefor having non-circular recesses in their outer faces with the axial bottom portions of said plugs adapted to constitute thrust bearings and bearing bushings fitting in said recesses.

2. A conveyer roller comprising a tubular body, end plugs therefor having non-circular`y recesses in their outer faces with the axial bottom portions of said plugs adapted to cone stitute thrust bearings and bearing bushings Y with peripheries fitting in said` recesses and bottoms of said recesses. I A

"3. A roller conveyer comprisingV` spaced with spaces between vsuch bushings and thef supportingrrails, oppositely disposed spaced bearing spindles .mounted on said rails, and conveyer rollers rotatably mounted on said;

spindles, said rollers Comprising a. tubular body having end plugs With non-circular recesses in their outer faces against the bottoms of which the ends of said spindles bear7 and Y non-circular bushings tting in said recesses and oonstitutingbearings for said spindles.

4. Al roller convey-er comprising spaced supporting rails, oppositely disposed spaced bearing spindles adjust-ably mounted on said rails, and conveye'r rollers rotatably 'mounted v Y on said spindles, said rollers comprising a zo Y.

tubular body having end plugs With non-circular recesses in their outer faces against the bottoms of which the ends of said spindles bear, and non-circular bushings tting in said recesses and constituting bearings for said spindles.
